This invention relatesto a can adjusting or reshaping machine, and has for one of its ob ects to provide a novel machine of this character through the medium of which cans which, due to their dent or crushed condition, areunfit for use by canneries, may be easily and quickly restoredto their original or useful condition at the canneries.

The invention has for a further object to provide a machine of the character stated through the crushed cans medium of which dented or of different sizes may be reprovide a machine of which shall b the character stated e' simple, durable and capable of being manufactured and sold at a low cost.

WVith the foregoing and other objects in view, the nature of which will appear as the description proceeds,v the invention consists in the construction, combination and arrangeand claimed, panying draw Figure 1 is a nent of parts hereinafter fully described and illustrated in the accomings, whereln top plan v1ew of a can adjusting or reshaping machine constructed in accordance with my invention;

The adjusti ng or reshaping machine comprises a table 1 which is of circular formation in plan and is supported by four equally spaced legs 2. The table lrests adjacent its edge upon the legs 2, and is secured to the legs by bolts 3. The legs 2 are of inverted U-form in elevation. The lower cross bars 4 of the legs 2 are adapted to rest upon a floor, bench or the like, and provide means through the medium of which the machine may be secured toits support by bolts 5. The 0 sides 6 of the legs2 are connected adjacent their upper ends by cross bars 7, and their upperends are outturned to provide lugs 8 tor'the reception of the bolts 3.

The table 1 is provided at i a pivot'support 9 which is of annular formation in plan and extends upwardly from the table. The lower portion or the pivotsupport 9 is arranged in an opening 10in the table 1, and "is welded'or otherwise rigidly 7 secured to the wall of the opening. The pivot support 9 is provided with a handle 11 which extends diametrically across the same, and is welded or otherwiserigidly secured to the support. An annular series of can adjust ing or reshaping means 12, 12a, 12b and 120 is carried by the table 1. These 'rnean's 12-120 are arranged in equally spaced relation outwardly of the pivot support 9, and the respective means are located adj aoent the $9 respective legs2. These means 1212'o are similar except as to sizes, their sizes being such as to adapt themto' adjust or reshape No; 1, No. 2,'No. 2 and No. 3cans, re-

"spectively. u

'Each of the can adjusting or reshaping means 12-120 comprises a-eylindrical core 13 which extends upwardly vfrom the tabie land consists oftwo similar upright sections 14:. The core sections 14 are provided at their lower ends with outer semi-circular flanges 15. The wall of a circular opening 16 formed in the table 1, is rabbeted toprovide an annular recess 17 for the reception @5 of the lower ends of the core sections 14. The flanges .15 slidably restupon the horizontal wall of the recess 17 and the-diameter of the vertical wall of the recess is greater than the diameter of the flanges 15 so'as to permit the 9 ts center with 64'! core sections 14 to be adjusted radially outward with respect to each other.

The core sections 14 are held against upward displacement by a ring 18 which is re cessed into the upper side of the table 1 and over-lies the flanges 15, the retaining ring being secured to the table by bolts 19. The core sections 14 have inclined inner or 0 posing sides 20 which converge in a downward direction, and they are provided in said sides thereof with passages'21 extend-- ing vertically therethrough and provided with vertical bottom walls.

A downwardly tapered wedge 22 is arranged between the core sections 14 in contact with the inclined sides 2O 01' the sections, and is fixed to the upper end of a bar 23 which is slidably mounted in the passages 21. The bar 23 constitutes an operating element for the wedge 22, and is guided in its movements by the walls of the passages 21. The bar 23 is greater in length than the core sections 14 and extends downwardly through the opening 16. A lever 24 which is arranged below the table 1, is pivotally connected at one end, as at 25, to a lug 26 extending downwardly from the table and secured thereto by bolts 27. The free end of the lever extends outwardly beyond the table 1 and is arranged between the sides 6 and above the cross bar 7 of the adjacent leg 2. The lever 24 is provided between its ends with a recess 28 for the reception of the reduced lower end 29 of the bar 23, and it is connected to this end of the bar by a pivot bolt 30.

From the foregoing it will be apparent that the core 13 is of the expansible type, that it is positively expanded by the downward movement of the wedge 22, and that the wedge may be manually moved downwardly to effeet the expansion of the core and moved upwardly to permit the core to be contracted through the medium of the lever 24 which. is adapted to be manually operated.

When it is in contracted condition, the core 13 is smaller diametrically than the inner diameter of the dented or crushed can to be restored to its original or useful condition. After the can has been applied to the core 3 in an inverted position, the wedge 22 is moved downwardly to expand the core, with the result that the can will berestored to its original or useful condition. After the can has been restored to this condition, the wedge 22 is moved upwardly. This movement of the switch 22 releases the core sections 14 for contraction and also moves the reshaped can upwardly with relation to the core sections, to the end that the can may be readily withdrawn from the core.

The can, which is designated 31, is held in a matrix 32 during the expansion of the core 13 to effect the restoration of the can. The matrix 32 comprises twoupright semicylindrical hollow sections 33 which are fully open at their lower ends and closed at their upper ends. The top walls 34 of the matrix sections 33 are provided in their lower sides with semicircular grooves 35 for the reception of the upwardly extended portion of the bottom bead 36 of the can 31. The upper portions of the inner lateral sides of the matrix sections 33 are provided with semicylindrical recesses 37 which communicate with the grooves 35 and are provided for the reception of the outwardly directed pcrtions of the can bead 36. The remaining or lower portions of the inner lateral surfaces of the matrix sections 33 have a diameter cor responding to the normal outer diameter of the can, and these portions surround and contact with the major portion of the side wall of the can when the matrix sections are in closed relation. The matrix sections 33 are arranged in relatively closed relation about the can 31 on the core 13, and to permit them to be moved into opened position and away from the core so as to permit the can to beapplied to and removed from the core, they are carried by levers 38 which are pivotally and slidably connected to the support 9.

The levers 38 are provided with semicircular portions 39 which surround the matrix sections 33 and are formed integrally there-- with. The inner ends of the levers 38 pass through openings 40 in the support 9, and are pivotally and slidably connected to the support by bolts 41 which are carried by the support and pass through slots 42 formed in. and extending longitudinally of the inner ends of the levers. The outer or handle ends of the levers extend radially beyond the table 1 so as to permit them to be readily grasped when it is desired to move the matrix sections 33 inwardly and hold them in can embracing relation or when it is desired to move them into can releasing relation. The pivotal and slidable connections between the levers 38 and the support 9 permit the matrix sections 33 to be moved inwardly and out wardly or laterally with respect'to the core 13, and thus adapt them to be readily moved into closed or can holding relation or into opened or can releasing relation.

From the foregoing description, taken in connection with the accompanying drawings, it should be apparent that when it is desired to restore a dented or crushed can to its original or useful condition, it is only necessary to place the can in an inverted position upon the core adapted to receive the same, then move the matrix sections 33 into closed or can holding relation, and then move the lever or crushed portions of the can, and the matrix 32 insuring the reshaping of the can to its original condition and preventing any upward displacement thereof from the core.

It should also be apparent that the can restoring means 12-120 are so arranged upon the table 1 that they may be simultaneously usedby difierent operators without one interfering with the other.
